5.3.5. Check of a hydraulic pusher
Check of a pusher carry out in case of suspicion in its malfunction (cottons, deterioration of operational characteristics). Warm up the engine during 2 mines at frequency of rotation of a cranked shaft of 2500 mines — 1.
Stop the engine and uncover heads of the block of cylinders. Press by means of a wooden or plastic core with the rounded-off end a pusher; thus the cam of a camshaft should be turned by an occipital part to a pusher. If a free wheeling of a pusher more than 0,1 mm prior to the beginning of valve opening, replace a pusher. At installation of the new pusher which previously filled with oil and has been pumped over, start up the engine not earlier than what through 30 mines not to allow blows of valves on pistons.
